Charm++ parallel programming system

Hello everyone,

I would like to template a new message type by a variable type so that I 
can treat it as a generic variable container. However, I'm having a bit 
of trouble. The following code is in my module file:

template<typename value_t> message ValueMsg;

and the commensurate implementation is:

template<typename value_t>
class ValueMsg : public CMessage_ValueMsg<value_t> {
public:
  value_t value;
  ValueMsg() { }
  ValueMsg(value_t v) {
    value = v;
  }
};

In the linking stage of compilation, I get a bunch of errors of the 
following type:

In function `CMessage_ValueMsg<int>::operator delete(void*)':
/home/jmiller/programming/charmploration/fibonacci-futures/fib.decl.h:105: 
undefined reference to `CMessage_ValueMsg<int>::dealloc(void*)'
/home/jmiller/programming/charmploration/fibonacci-futures/fib.cpp:53: 
undefined reference to `CMessage_ValueMsg<int>::operator new(unsigned 
long, int)'

Is there something I'm doing wrong? Or is templating messages simply not 
possible?

Alternatively, is it possible to use the PUP framework to define the 
serialization for a message, if I want to, for example use futures?

Thanks in advance for your help!

Best,
